Sprites, Jets, and Glowing Balls: The Science of Lightning
Ever wonder how lightning works? Scientists are still figuring it out, but what we do know is fascinating. Learn about positive and negative lightning, red sprites, blue jets, and ball lightning...
========== Whether it’s up in the sky during a thunderstorm,
or helping send a DeLorean back to the future, lightning is a beautiful, dangerous phenomenon. Most people picture lightning as a brilliant
